A wmn'nnss APPARATUS.

Toczlw hoiait concern: it v Be it known that I, HENRY H. Hyman, acitizen of the United States, and a resident of Hollywoodpstate ofCalifornia, have invented a new and useful Improvement in WirelessApparatus, of which the following is a specificatiom'the principle ofthe inven-- tion being 'hereinexplained, and the best mode inwhich Ihavecontemplated apply-v ing, that principle, so. as to distinguish it ifrom other inventions The present invention relates to mechanismformechanically.locking an electrical.

circuit so that it can be closedonly upon the closingand openingofanother circuit according to a predetermined scale; It is particularlyadapted to be usedjin connection with circuitsfor exploding mines andthe necessary intervals of time for closing and opening thecircuitrcontrolling the mechani- I anism embodying the invention, suchdiscal lock and operating mechanism for closing the working fcircuit.To. the accomplishment of the foregoing and related ends, said.

invention, then, consists of theimeans hereinafter fully described andparticularly pointed out in theclaims;

M The annexed drawing and the following description set forth indetailcertain mechclosed means constituting, however, but one of,various mechanical forms in which the principle ofthe invention may beused.

,. In said annexed drawings circuit connectionsof the device; Fig. 2 isa top plan view {of the mechanical locking means; Fig. 3 .is a sectiontaken on the line 3-;3, Fig. 2 Fig. 4 is a section on the line 4-4, Fig.3 and Fig. 5 is-a section on the I line 55, Fig. 2.

The locking mechanism consists of a base member 1 having standards 2thereon, carryinga housing 7 in which is mounted a 7 lead screw 3, whichhasone end 4 extending through the bearing, agear 5 being mount- 2 ed onsaid extending end. A carriage 6 is 'slidably mounted'on the housing 7,and in the lowerv part of the carriage is mounted a mutilated nut 8,which is adapted to engage specification of Iletters llatent.

with the lead screw 3 to drive the carriage 1. along the same. Thismutilated nut has a pin 9 extending downwardly in-a slot 10in thecarriage, a spring 11 being mounted in such slot to maintain themutilated nutin engagement withythe lead screw 3. Adjacentone end, ofthe base,and;mounted on an extendingarm 12 thereof, is a motor 13carrying a, gear 14 on thejouter end of its,

shaft, which gear meshes witha large idler gear l5,which..in turn. is inmesh with the gear 5 on shaft end 4 in orderto operate the lead screw 3.i

:The movable carriage is provided with upwardly extending arm 20 havinga hori-,

z'ontal portion 21, to which is pivotally. 5 mounted a guide arm 22normallyheld in the position, shown in Fig: 3by means of a} coil spring23. On the'uppeninsulation plate 24 of the base are pivotally mounted,

two guides 25 and 26 in the path of movement of the guide arm-.22. Athirdguidel27.

.is mounted parallel'to the lead screw Band the guide 25 isadapted tocbeheld against the guide 27 by means of a coil spring 28. The guide 26hasoneendheld against the guide 25 by means of theicoil spring 29.:Adja-v cent the motor end of the plate 24 is mount-1 ed a spring contactmemberBO, which is normally spaced from an adjustable contact. screw 31,which passes through a block 32,- 1

and is provided with a lock nut-33to hold itinany desired position. Whenthe car riage is moved from the position shown in Fig.2 to the left, theguide arm 22 is moved.

along between the guides 27 and 25, forcing the guide 25- outwardlyuntilthe arm 22 passes the end 34 of the guide 25. As soon as thismovement has been completed, if the carriage is then moved in theopposite Idl-- rection, the arm 22 will pass along the outer side of theguide 25.until it contacts'and forces outwardly the guide 26 and passestherebetween. It the carriage at this time I is then moved again to theleft, then the guide arm 22 will cam along the outer face of the guide26 until it strikes the contact member 30, which will force this againstthe contact screw 31. I

Extending laterally from the. arm 20 of the carriage is a pin 36, whichis adapted to switch X.

contact a resilient arm 87 to move the same away from an adjustablecontact screw 38 held by means of a lock nut 39 in a contact bushing 40.The lower part of the carriage is adapted, in the position shown in Fig.2, to contact a resilient arm 41, which normally is in contact with anadjusting screw 42, held in a contact bushing 43 by means of a lock nut44.

In the normal position of the device, that shown in Fig. 2, the switchA, composed of resilient arms 41 and the contact screw 42, will beopened, while the switch B, comprising the arm 37 and the contact screw38, will be closed, and the switch C, with the resilient arm 30, will beopen. As the switch C controlsthe circuit to be operated, then in orderto close this'switch it is necessary to move the carriage and the guidearm to the left until it passes the first guide, then to the right untilit passes the end of the second guide, and then again to the left untilit contacts with and closes the switch C. It will thus be seen that ifthe motor runs at a constant speed the time necessary for the carriageto be moved past the various guides will be determined to within veryclose limits, and unless these limits are adhered to the switch C cannotbe closed, as movement to the left, beyond the necessary point to passthe guide arm, will open the switch B, which is adapted to open themotor circuit to prevent further forward movement. It will be seen inFig. 2 that the guide arm will pass along the outer face of the guide 25in its return movement and will trip over the rear end of the same toreturn to the normal position at the right, as shown in Fig. 2.

Turning to the wiring diagram, there is shown the ends of a wirelessreceiving circuit 50, to which is connected an audion 51, adapted toreceive the wireless waves to control the circuit 52, including thebattery 53 and a relay 54. hen energized, this relay 54 actuates theswitch 55, which closes a circuit 56 through a battery 57 and a secondrelay 58. This relay 58, when actuated, closes the switch 59, whichactuates the next circuit containing the battery 60 and a relay 61 toclose the motor circuit through the hen the device is in its normalposition the switch X will be drawn by the spring 62 against the contact63. This contact G3 is connected by a wire 64 with the battery 65, andthe wire 66 to the resilient contact arm 41 of the switch A, which isnormally open, and then back through the wire 67, through the reversingrelay 68 to the movable switch member X. Whenever the switch X is closedthrough the contact 69 the motor circuit is closed through the wire 70,the switch B which is normally closed, the wires 71 and 72, the armature73 and the wire 74, through the contact point 7 5 to one end 79 of theinsulated armature of the .relay, and thence out through the wire 81,through the motor field 82, the wire 83, the battery 84 through the end80 of the relay armature, and then through the contact point 76 and thewire 85 back to the movable switch member.

As soon as the switch X is opened the circuit through the relay and theswitch A will be closed, and the armature to the relay will be pulleddown, to close the contacts 78, 79, 80 and 77. This, as is readily seen,will reverse the current through the motor armature to move the carriageto the right, as shown in Fig. 2. As soon as the carriage reaches theend of its travel, the switch A will be open, reversing the relay toopen the motor circuit.

The device includes a switch C in circuit with a battery 86 and aninduction coil 87 by means of the wires 88 and 90. The other side of theinduction coil is connected to a spark gap 89, which will be the workingcircuit which is adapted to be operated either to explode a mine or tooperate any other desired device.

It will be seen that the carriage must be moved, from the position shownin Fig. 2, forwardly until it just passes the end of the first guide,and then. must be reversed until it just passes the end of the secondguide, and then again moved forwardly until it contacts with the member30 to close the switch C. Whenever the switch X is closed through thecontact 69 the motor will move the carriage forwardly and this switch Xwill remain closed as long as the operator of the wireless sendingapparatus maintains certain wave lengths through the audion, which willin turn close the relays to actuate the switch X. Thus the operator ofthe wireless sending apparatus, who knows the lengths of time that ittakes the motor to move the carriage forwardly until it just passes theguide, and then the length of time necessary for it to reverse and passthe end of the second guide, is enabled to operate the device throughthe audion. if someone else tries to operate it, movement of thecarriage too far to the left opens the switch B and thereby stops themotor. Then if the switch X is opened, the motor will be reversed andwill move back until the switch A is opened which will operate thereversing relay to stop the motor which will remain idle until theswitch X is again closed. In its return movement the guide arm tripsover the right end of the guide 25 to return to its normal position. Itwill thus be seen that only by a series of predetermined movements ofthe carriage can the device be operated to close the working circuitthrough the contact member 30. The variations in the predeterminedmovements are unlimited, as more than two guides may be used, and thelengths of these guides may be varied so that any my invention may 1 theone explained, change vided the means stated-by number of difl'ere tcombinations maybe Worked out.
